Can MS & Sony just simply make next gen fully BC?

Well Sony hasn't attempted to make a PS3 emulator, but I'm not arguing its impossible to make that happen on PS4. The consensus has been the PS4 CPU just doesn't have the power needed. The PS3 emulator on PC requires a powerful CPU to operate at full speed but that's just an example that exist right now.

If it's a question of power... Remember that Microsoft isn't actually doing pure emulation in it's backwards compatibility efforts.
So the Emulation overhead isn't even a factor. - They aren't doing Emulation-PC-Style, consoles certainly do not have the horsepower for that.

And I will quote you on the last bit... Because now you are just contradicting your own statements:

I think you're comparing the PC emulators, which isn't a fair comparison because that isn't equal optimization.

I watched the DF video discussing how Xbox 360 BC works and he says the hardware is handling some functions outside of emulation. Maybe going that route helps with some of the overhead of emulation but the X1 hardware itself is still doing heavy lifting on emulation and why X1X gets better results.

Correct. Microsoft has baked in some hardware support for the Xbox 360 (Mostly just texture format stuffs) into the Xbox One's SoC which can lend a hand to backwards compatibility, but it's not entirely necessary.

But what Microsoft is doing is... Leveraging their Multi-OS approach by using virtualization so that they can run the Xbox 360/Original Xbox's Operating Systems alongside the Xbox One's Operating Systems. - That cuts a massive chunk of the Emulation overhead.

Microsoft is then also abstracting as much as it can... And possibly even using a form of binary translation.

And we know that they are repackaging their games, hence the enforced download of all Backwards Compatible games... Which is in stark contrast to the XBox 360's Backwards compatibility scheme as you would only download a tiny profile that is only a couple megabytes on that console to plug into the Emulator.

Meaning the CPU is pretty irrelevant, the Jaguar CPU's are vastly superior to that of Cell and Xenon anyway... Especially once you start to leverage some of the newer instructions. - And like I eluded to prior, the more Multi-threaded a game is, the better it is to Emulate... As no longer does timing and keeping everything in sync is as important.

At the end of the day though... Before Microsoft launched their Xbox One backwards compatibility scheme, I often argued it was entirely possible to emulate the Xbox 360 on the Xbox One... They just couldn't take a brute force approach... And it turned out I was correct. - And I argue the same reasoning for the Playstation 3.
